Consequently, the automotive industry is demanding more compact and efficient integrated thermal management modules. Utility Model Content

[0081] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0082] Combine Figures 1 to 10According to an embodiment of the present invention, a thermal management device 100 includes a compressor 10, a first valve 31, a second valve 32, and a heat exchange liquid storage assembly 20. The first inlet of the first valve 31 is connected to the exhaust chamber 1011 of the compressor 10, the second inlet of the second valve 32 is connected to the bypass port of the first valve 31, and the second outlet of the second valve 32 is connected to the suction chamber 1012 of the compressor 10. The third inlet of the heat exchange liquid storage assembly 20 is connected to the first outlet of the first valve 31, and the third outlet of the heat exchange liquid storage assembly 20 is connected to the exhaust chamber 1011 of the compressor 10. The first valve 31 is configured to control the refrigerant in the exhaust chamber 1011 to selectively flow to the second inlet of the second valve 32 and the third inlet of the heat exchange liquid storage assembly 20. By adjusting the opening of the first valve 31, the exhaust pressure can be controlled. By controlling the exhaust pressure, the input power of the compressor 10 can be indirectly changed, thereby changing the cooling and heating power of the thermal management device 100.

[0083] Among them, the compressor 10 can inhale air from the intake chamber 1012 and send it out from the exhaust chamber 1011 after compression. The compressor 10 is mainly formed by a collection of related compressor 10 components that can compress low-pressure refrigerant into high-pressure refrigerant. The heat exchange liquid storage component 20 is mainly formed by a collection of related heat exchange components that can achieve temperature control. The integration and structural strength of the compressor 10 and the heat exchange liquid storage component 20 are improved, and it also helps to improve the total volume of the internal flow path of the compressor 10 and the heat exchange liquid storage component 20, which is convenient for reducing the amount of refrigerant added.

[0084] According to the thermal management device 100 of the present embodiment, the return flow path of the first valve 31 and the second valve 32 increases the total flow rate of refrigerant flowing through the compressor 10, thereby increasing the output power of the compressor 10 and improving the heating capacity of the system. Adjusting the opening of the first valve 31 can adjust the exhaust pressure of the compressor 10, thereby increasing the output power of the compressor 10 and achieving a rapid heating effect.

[0085] The first valve 31 and the second valve 32 of the present invention may be electronic expansion valves, proportional valves, or throttle valves. Furthermore, the thermal management device 100 of the present invention may be used in vehicles or other equipment requiring temperature regulation. While the present invention is primarily described with reference to vehicles, this does not limit the scope of protection of the present invention.

[0086] In the vehicle, the thermal management device 100 is mainly connected to the vehicle's functional systems and is used to control the temperature of the vehicle's functional systems. The vehicle's functional systems can be electric drive systems, battery systems, temperature control systems or dehumidification systems in the passenger compartment, etc., so as to utilize the refrigerant in the thermal management device 100 for heat exchange and realize effective temperature control of the vehicle's electric drive system, battery system, and passenger compartment.

[0087] In some embodiments of the present invention, the thermal management device 100 has a first working mode, in which the first valve 31 controls the flow of refrigerant in the exhaust chamber 1011 to the third inlet of the heat exchange liquid storage assembly 20. Specifically, in the first working mode, the thermal management device 100 operates for ordinary cooling and heating, and the high-pressure refrigerant compressed by the compressor 10 passes through the first valve 31 (which can be in a fully open state) and enters the heat exchange liquid storage assembly 20. The refrigerant exchanges heat with the refrigerant in the heat exchange liquid storage assembly 20, and uses the refrigerant to exchange heat with the functional systems in the vehicle, which can meet ordinary cooling and heating conditions. In this mode, the second valve 32 can be kept in a closed state, and the heat exchange between the refrigerant flow path in the heat exchange liquid storage assembly 20 and the medium in the water flow path can meet the basic functions of the thermal management device 100.

[0088] In addition, reference Figure 3 and Figure 4 , the thermal management device 100 also has a second working mode. In the second working mode, the first valve 31 controls the refrigerant in the exhaust chamber 1011 to flow to the third inlet of the heat exchange liquid storage component 20 and the second inlet of the second valve 32. Specifically, in the second working mode, the thermal management device 100 can achieve extremely low temperature requirements. When the ordinary refrigerant cycle cannot meet the cooling and heating requirements of the system, a part of the refrigerant sent out from the exhaust chamber 1011 can pass through the first valve 31 (which can be partially open) and enter the heat exchange liquid storage component 20. The refrigerant exchanges heat with the refrigerant in the heat exchange liquid storage component 20, and uses the refrigerant to exchange heat with the functional system in the vehicle, and finally flows back to the intake chamber 1012; another part of the refrigerant sent out from the exhaust chamber 1011 passes through the first valve 31 (partially open) and the second valve 32 (partially open) and also enters the intake chamber 1012. The heating cycle is completed. In this mode, the second valve 32 can be kept in an open state, which can meet the extremely cold requirements of the thermal management device 100. The attached Figure 3 and Figure 4 The refrigerant circulation path is shown in FIG.

[0089] In some embodiments, the compressor 10 has a first end 1021 and a second end 1022 that are opposite each other along the axis. The second end 1022 of the compressor 10 may be provided with an intake port 1203 and an exhaust port 1204. The heat exchange liquid storage assembly 20 is connected to the compressor 10 and communicates with the exhaust port 1204 and the intake port 1203. Furthermore, the heat exchange liquid storage assembly 20 and the compressor 10 are distributed along the axis of the compressor 10, with the intake port 1203 and the exhaust port 1204 being provided on the end surface of the second end 1022 of the compressor 10. This facilitates the connection of the compressor 10 to the heat exchange liquid storage assembly 20.

[0090] Combine Figures 1 to 13The present invention further provides a compressor 10, comprising a housing 11 and an exhaust distribution member 12, connected to the housing 11. The first valve 31 and the second valve 32 of the aforementioned embodiment can be disposed on the exhaust distribution member 12, and the heat exchange and liquid storage assembly 20 can be connected to the exhaust distribution member 12. The exhaust distribution member 12 can be used to distribute the refrigerant discharged from the compressor 10, thereby improving the integration of the compressor 10 and facilitating assembly and maintenance of the compressor 10.

[0091] In addition, if Figures 5 to 13 The present invention also provides an exhaust distribution component 12, which is used to connect the aforementioned shell body 11. The exhaust distribution component 12 can be provided with a first installation cavity 1031 and an exhaust flow channel 1041. The exhaust flow channel 1041 connects the exhaust cavity 1011 and the first installation cavity 1031. The first valve 31 is provided in the first installation cavity 1031. The exhaust flow channel 1041 can deliver the refrigerant from the exhaust cavity 1011 and guide the refrigerant delivered from the exhaust cavity 1011 to flow into the first installation cavity 1031. By providing the first installation cavity 1031 in the exhaust distribution component 12, the integration of the compressor 10 can be improved, and the pipeline size can be reduced, thereby reducing the amount of refrigerant, reducing the safety risk caused by refrigerant leakage, and improving the stability and safety of the thermal management device 100.

[0092] Among them, the exhaust chamber 1011 is provided with a lubricating oil separation chamber 1205, and the exhaust flow channel 1041 connects the lubricating oil separation chamber 1205 and the first installation chamber 1031. The lubricating oil separation chamber 1205 can be used to separate the refrigerant and the lubricating oil. After the refrigerant is compressed by the compressor 10, it is sent to the exhaust chamber 1011. Since the speed of the compressor 10 is relatively high during operation, it is necessary to provide lubricating oil to improve the stability of the operation of the compressor 10. Of course, after the lubricating oil is provided, the refrigerant discharged from the compressor 10 during operation will inevitably carry lubricating oil. The refrigerant carrying lubricating oil enters the exhaust chamber 1011 and passes into the lubricating oil separation chamber 1205. The lubricating oil and the refrigerant will be separated in the lubricating oil separation chamber 1205, wherein the lubricating oil remains in the exhaust chamber 1011 (or the lubricating oil separation chamber 1205), while the refrigerant will be sent out through the exhaust flow channel 1041 and sent to the first installation chamber 1031, and then the first installation chamber 1031 is used to control the flow direction of the refrigerant. By providing the exhaust flow channel 1041, the refrigerant flow rate in the system can be increased, thereby improving the performance of the thermal management device 100. Furthermore, the lubricating oil separation chamber 1205 can separate the lubricating oil carried by the refrigerant, thereby increasing the amount of refrigerant in the refrigerant flow path and improving the operating performance of the compressor 10. This also facilitates the return of the separated lubricating oil to the compressor 10 for lubricating the compression unit 14 therein, thereby reducing the amount of lubricating oil used in the thermal management device 100.

[0093] Optionally, the exhaust channel 1041 is configured as a straight channel extending obliquely from bottom to top. The lower end of the exhaust channel 1041 communicates with the lubricating oil separation chamber 1205, and the upper end of the exhaust channel 1041 forms a first mounting cavity 1031 that extends through the outer surface of the exhaust distributor 12. Furthermore, the exhaust distributor 12 is provided with a first cylindrical portion, within which the lubricating oil separation chamber can be located. With the upper end of the exhaust channel extending through the outer surface of the exhaust distributor 12, the exhaust channel can be constructed by drilling a hole through the outer surface of the exhaust distributor 12. Furthermore, the open upper end of the exhaust channel facilitates installation of the first valve 31 within the first mounting cavity 1031, simplifying the assembly of the first valve 31. Furthermore, the installation of the first valve 31 can be used to seal the open end of the exhaust channel 1041, thereby improving the integration of the compressor 10.

[0094] In addition, the end face of the exhaust distribution component 12 is provided with an exhaust port 1204, which is connected to the first installation cavity 1031, and the exhaust port 1204 is connected to the third inlet of the heat exchange liquid storage component 20. The exhaust port 1204 can facilitate the connection between the exhaust distribution component 12 and the heat exchange liquid storage component 20, simplify the pipeline setting of the thermal management device 100, and facilitate the production, assembly and maintenance of the thermal management device 100. In addition, the exhaust distribution component 12 can be connected to the heat exchange liquid storage component 20 as an integrated structure. For example, the exhaust distribution component 12 and the heat exchange liquid storage component 20 are stacked and docked along the axis of the compressor 10. At this time, the exhaust port 1204 can be docked with the third inlet of the heat exchange liquid storage component 20 along the axis of the compressor 10, which can further simplify the structure of the thermal management device 100 and facilitate installation. In addition, it can also shorten the length of the refrigerant pipeline and reduce the amount of refrigerant used.

[0095] Combine Figures 11 to 13 In some embodiments, the exhaust distribution member 12 is provided with a second installation cavity 1032 and a first bypass channel 1201. The first bypass channel 1201 connects the first installation cavity 1031 and the second installation cavity 1032, and the second valve 32 is disposed in the second installation cavity 1032. The first bypass channel 1201 can be used to allow refrigerant to flow from the first installation cavity 1031 to the second installation cavity 1032. Thus, when the first inlet of the first valve 31 is connected to the bypass port, the refrigerant delivered from the exhaust cavity 1011 will flow from the exhaust channel into the first bypass channel 1201. Thus, the first bypass channel 1201 is used to bypass the refrigerant, thereby increasing the amount of refrigerant return air and optimizing the performance of the thermal management device 100.

[0096] Optionally, the exhaust flow channel 1041 is configured as a straight channel.

With one end of the first bypass flow channel 1201 penetrating the outer surface of the exhaust distribution member 12, an exhaust channel can be constructed by drilling a hole through the outer surface of the exhaust distribution member 12. Furthermore, with the first bypass flow channel 1201 open, the first sensor 61 can be conveniently mounted at the open end of the first bypass flow channel 1201.

The second channel 1302 can be used to guide the refrigerant in the first channel 1301 outside the suction chamber 1012 to the suction chamber 1012, thereby facilitating suction of the suction chamber 1012.

[0124] In some embodiments, the first channel 1301 is configured as a linear channel extending perpendicular to the axis of the compressor 10. One end of the first channel 1301 penetrates the outer surface of the low-pressure housing 13 and is provided with a second plug 52. This facilitates the molding of the first channel 1301, simplifies the structure of the low-pressure housing 13, and reduces the difficulty of processing the low-pressure housing 13.

The second channel 1302 can be constructed by drilling a hole through the outer surface of the low-pressure housing 13, and the open end of the second channel 1302 can be sealed with the third plug 53 to prevent refrigerant leakage.

[0127] Optionally, the second channel 1302 is connected to the lower portion of the suction chamber 1012, so as to facilitate the suction of the compressor 10.

[0128] In some embodiments, the low-pressure housing 13 further includes a third mounting cavity 1033, which communicates with the communication channel. The compressor 10 further includes a refrigerant filling valve 34, which is located in the third mounting cavity 1033.

The refrigerant filling valve 34 can be used for vacuuming the compressor 10 and filling the refrigerant.

[0129] In some embodiments, the low-pressure housing 13 further includes a fourth mounting cavity 1034, which is connected to the communication flow channel. The compressor 10 further includes a second sensor 62, which is disposed in the fourth mounting cavity 1034.

[0130] In some embodiments, an electric control chamber for mounting electronic components is provided at the first end of the compressor 10. The electronic components, the electric control chamber, etc. can be integrated into the compressor 10, thereby increasing the integration level of the compressor 10 and reducing the size of the compressor 10.

[0131] Furthermore, the electronic device includes a high-voltage connector 133, which is installed in the electric control cavity and extends out of the electric control cavity for connecting to a high-voltage wiring harness; and / or, the electronic device includes a low-voltage connector 134, which is installed in the electric control cavity and extends out of the electric control cavity for connecting to a low-voltage wiring harness; and / or, the electronic device includes a stator connector, which is installed in the electric control cavity and extends out of the electric control cavity for connecting to the stator 151; and / or, the electronic device includes an integrated circuit board 161, which is installed in the electric control cavity and electrically connects the high-voltage connector 133 and the low-voltage connector 134. A stator connector mounting hole 1306 is designed on the low-voltage housing 13 for sealing and insulating the stator connector and the low-voltage housing 13. Through the stator connector mounting hole 1306, communication and electrical conduction between the integrated circuit board 161 and the stator 151 can be achieved.

[0132] Optionally, the first end 1021 of the compressor 10 is provided with an end plate 131 and an end cover 132 covering the end plate 131, and the end cover 132 is farther away from the second end 1022 of the compressor 10 than the end plate 131, wherein the end plate 131 is provided with a high-voltage connector mounting hole 1304, a low-voltage connector mounting hole 1305, a stator connector mounting hole 1306, a power device heat dissipation surface 1303 and / or a cover mounting hole 1307, and the high-voltage connector mounting hole 1304 and the low-voltage connector mounting hole 1305 pass through the end plate 131 and are arranged on the outside of the suction cavity 1012. The low-voltage connector 134 can be located in the low-voltage connector mounting hole 1305, and the high-voltage connector 133 can be located in the high-voltage connector mounting hole 1304. Since the low-voltage connector mounting hole 1305 and the high-voltage connector mounting hole 1304 pass through the end plate 131, the wiring port of the high-voltage connector 133 and the wiring port of the low-voltage connector 134 can be located on the side of the end plate 131 facing the second end 1022, thereby facilitating the wiring of the compressor 10 and reducing the space occupied by the compressor 10, thereby improving space utilization. The heat generated by the power module 162 on the integrated circuit board 161 is efficiently conducted through the power device heat dissipation surface 1303. The heat conducted to the low-pressure housing 13 is released into the refrigerant through convection heat exchange between the low-pressure housing 13 and the refrigerant.

[0133] In addition, the end plate 131 is provided with stator connector mounting holes 1306, a power device heat dissipation surface 1303, and / or a cover plate mounting hole 1307. This facilitates the installation of electronic components and circuit boards, as well as the heat dissipation of power devices, thereby improving the operational stability of the compressor 10 and optimizing its performance.

[0134] In addition, the end face formed by the second end 1022 is connected to the surface of the heat exchange liquid storage component 20, so that the exhaust port 1204 and the intake port 1203 integrated in the second end 1022 are connected to the refrigerant flow path on the heat exchange liquid storage component 20, ensuring the normal circulation of the refrigerant in the thermal management device 100, while reducing the use of connecting pipes and reducing the overall volume of the thermal management device 100; the integrated assembly of the compressor 10 and the heat exchange liquid storage component 20 is achieved by means of, for example, bolt connection, snap connection, and plug-in connection, thereby improving the connection reliability of the compressor 10 and the heat exchange liquid storage component 20, and thereby further ensuring the circulation reliability of the internal refrigerant.

[0135] The first end portion 1021 is used to connect to the vehicle power supply. When the first end portion 1021 and the second end portion 1022 are arranged opposite each other, that is, when the heat exchange liquid storage assembly 20 is located on the side of the compressor 10 away from the first end portion 1021, the installation space on this side can be reasonably utilized. In other words, it can effectively reduce the space occupied on the other side of the thermal management device 100, freeing up space for the assembly of other components and reducing interference. Of course, in other embodiments, depending on the specific distribution positions of the exhaust port 1204 and the intake port 1203 of the compressor 10, the heat exchange liquid storage assembly 20 can semi-surround the compressor 10, or be connected to the peripheral side of the compressor 10.

[0136] The first end portion 1021 is provided with a connector for connecting to a power source. The connector includes a high-voltage connector 133 and a low-voltage connector 134 spaced apart from top to bottom.

[0137] In some embodiments, the compressor 10 is provided with an electric unit and a compression unit 14. The electric unit is provided in the first housing portion 111. The electric unit includes a stator 151, a rotor 152 and a main shaft 153. The main shaft 153 is connected to the rotor 152. The stator 151 drives the rotor 152 to rotate. The main shaft 153 is transmission-connected to the compression unit 14, wherein one end of the main shaft 153 is connected to the compression unit 14 and is provided with a first balancing block 154; and / or, one end of the rotor 152 is away from the compression unit 14 and is provided with a second balancing block 155.

[0138] In combination with the above, the compressor 10 of the present invention may include: a low-pressure housing 13, a low-pressure connector 134, a high-pressure connector 133, an end cover 132, a mounting bracket 74, an exhaust distribution component 12, etc.

[0139] The high-voltage connector 133 connects to the vehicle's high-voltage wiring harness, providing high-voltage power to the compressor 10 and implementing the high-voltage system interlocking function. The low-voltage connector 134 connects to the vehicle's low-voltage wiring harness, providing low-voltage control signals to the compressor 10. The vehicle controls the compressor 10 and receives feedback signals from the compressor 10 through the low-voltage connector 134. The integrated circuit board 161 receives the control signals from the low-voltage connector 134 and converts the direct current from the high-voltage connector 133 into alternating current with adjustable frequency and voltage. This generates a rotating magnetic field through the coils of the stator 151. The rotating magnetic field causes the rotor 152 to rotate about the axis formed by the first and second bearings 173 and 174. A first balancing weight 154 and a second balancing weight 155 are mounted at the ends of the main shaft 153 and rotor 152, respectively. These balancing weights offset the unbalanced forces generated by the movement of the rotor 152 and compression element 14, reducing vibration in the compressor 10.

[0140] The compression unit 14 may include a fixed scroll and a movable scroll. The fixed scroll is relatively stationary with the shell body 11. The movable scroll and the rotor 152 are connected together through the main shaft 153. The movable scroll generates a spiral translation under the drive of the rotor 152. The refrigerant enters and exits the compressor 10 through the exhaust distribution component 12. The exhaust distribution component 12 is processed with an exhaust port 1204 and an intake port 1203. The refrigerant enters the compressor 10 from the intake port 1203 and flows out of the compressor 10 after exhaust. The first plug 51 and the exhaust distribution component 12, the second plug 52 and the third plug 53 and the low-pressure shell 13 in the utility model can be connected and fixed by welding or threading with a sealing ring 73.

[0141] Optionally, the low-pressure housing 13 is designed with a first bearing frame 171, in which a first bearing 173 is mounted, which supports the end of the main shaft 153. The low-pressure housing 13 is also designed with a second bearing frame 172, in which a second bearing 174 is mounted, which supports the end of the main shaft 153. A mounting bracket 74 is designed on the low-pressure housing 13 for securing the compressor 10 assembly to the vehicle. An accessory bracket and accessory mounting holes 701 are designed on the low-pressure housing 13 for securing other accessories of the refrigeration system.

[0142] Among them, the refrigerant enters the intake flow channel 1042 from the intake port 1203, enters the low-pressure cavity of the compressor 10 through the intake flow channel 1042, and flows through the stator 151 and rotor 152 of the motor in the low-pressure cavity and then enters the compressor 10 cavity formed by the movable scroll and the static scroll. The refrigerant compression process is realized in the movable / static scroll, and the high-pressure refrigerant gas is discharged from the central exhaust hole of the static scroll. The refrigerant breaks through the exhaust valve plate 141 and enters the exhaust distribution component 12. The refrigerant and lubricating oil are separated in the oil separation channel of the exhaust distribution component 12. The separated lubricating oil flows into the vicinity of the second bearing 174 through the return oil hole to lubricate the second bearing 174. The end of the oil separation channel is connected to the first valve 31 and the exhaust port 1204, and the exhaust pressure is adjusted by the first valve 31. The exhaust port 1204 is connected to the external heat exchanger to realize the heat and mass transfer functions between the refrigerant and the refrigeration system.

[0143] Integrated circuit board 161 receives control signals from low-voltage connector 134 and converts the direct current from high-voltage connector 133 into alternating current with adjustable frequency and voltage. This current then generates a rotating magnetic field through the coils of stator 151. The rotating magnetic field causes rotor 152 to rotate about the axis formed by first bearing 173 and second bearing 174.

[0144] In the technical solution of the present utility model, the integrated assembly of the thermal management device 100 and the connection of the internal flow path are realized by directly connecting the compressor 10 and the heat exchange liquid storage component 20, ensuring that the thermal management device 100 can realize temperature control of the functional system of the vehicle. Moreover, compared with using connecting pipes to connect various components, the number of connecting pipes can be reduced, the integration of the thermal management device 100 can be improved, and the total volume of the flow channel in the thermal management device 100 can be reduced, reducing the risk of refrigerant leakage. At the same time, the refrigerant filling amount can be greatly reduced and the structural strength of the device can be increased, thereby improving the safety of the use of the thermal management system. In addition, the assembly method of integrating the two assemblies can save assembly time of the thermal management system and meet the hierarchical assembly of the general assembly line.

[0145] like Figure 1 and Figure 2The present invention also provides a heat exchange liquid storage assembly 20, wherein the heat exchange liquid storage assembly 20 includes a liquid reservoir 21 and at least one heat exchanger. The liquid reservoir 21 and at least one heat exchanger are integrated into a whole. Furthermore, by integrating the heat exchange liquid storage assembly 20 into a whole, the assembly of the thermal management device 100 and the connection of the internal flow path are realized. Compared with using connecting pipes to connect the various components, the number of connecting pipes is reduced, the integration of the thermal management device 100 is improved, and the total volume of the flow channel in the thermal management device 100 is reduced, reducing the risk of refrigerant leakage. At the same time, the refrigerant filling amount can be greatly reduced and the structural strength of the device can be increased, thereby improving the safety of the thermal management system. It can also save assembly hours for the thermal management system and meet the hierarchical assembly of the general assembly line. The reduction in the refrigerant filling amount can increase the safety of the flammable and explosive thermal management system and improve the safety level of the entire vehicle.

[0146] Optionally, the liquid reservoir 21 and at least one heat exchanger are stacked along the axis of the compressor 10. This simplifies the flow path within the heat exchange processing assembly and reduces flow resistance. Furthermore, a desiccant and / or filter can be integrated within the liquid reservoir 21 to improve the operating performance of the heat exchange liquid storage assembly 20, increase the proportion of gaseous refrigerant in the refrigerant flow path, and optimize the performance of the compressor 10.

[0147] Optionally, the liquid reservoir 21 and the at least one heat exchanger are integrated into a single unit by welding or bolting, which can improve the stability and structural strength of the heat exchange liquid storage assembly 20 and ensure the sealing between the components to prevent refrigerant leakage, thereby improving the stability and safety of the heat exchange liquid storage assembly 20. In addition, the liquid reservoir 21 and the at least one heat exchanger can be connected to each other through internal flow channels to achieve refrigerant flow.

[0148] In some embodiments, a first observation window 211 is provided at the bottom of the liquid reservoir 21; and / or a second observation window 212 is provided on the side of the liquid reservoir 21. The first observation window 211 and the second observation window 212 are used to observe the refrigerant status inside the liquid reservoir 21 and at the outlet of the liquid reservoir 21. This facilitates observation of the internal status of the liquid reservoir 21, facilitating assembly and maintenance of the thermal management device 100.

[0149] The heat exchange liquid storage assembly 20 is provided with independent refrigerant flow paths and coolant flow paths. The second end portion 1022 of the compressor 10 is provided with an exhaust port 1204 and an air intake port 1203. The refrigerant flow path is connected to the compressor 10 through the exhaust port 1204 and the air intake port 1203, so that the refrigerant of the compressor 10 flows into the refrigerant flow path of the heat exchange liquid storage assembly 20 through the exhaust port 1204 and exchanges heat with the coolant in the coolant flow path. After the heat exchange, the refrigerant re-enters the compressor 10 through the air intake port 1203, completing a cycle. Optionally, the refrigerant flow path is provided between the third inlet and the third outlet.

[0150] There is at least one coolant flow path in the heat exchange liquid storage component 20, and each coolant flow path corresponds to each functional system, and is connected to the refrigerant flow path in a closed loop. In this way, the refrigerant in one refrigerant flow path is heat exchanged with the coolant in multiple coolant flow paths to achieve effective temperature control of the vehicle's electric drive system, battery system, and passenger compartment, which helps to improve the functional integration of the heat exchange liquid storage component 20, further simplify the system flow path, and reduce costs.

[0151] Each heat exchanger corresponds to a different functional system, enhancing the functional integration of the heat exchange reservoir assembly 20. By utilizing the structural characteristics of the heat exchanger, namely the close arrangement of the plates to form flow channels for the hot and cold fluids, the heat exchanger has a smaller footprint and occupies less space than other types of heat exchangers. This, combined with the stacked arrangement of the reservoir 21, can reduce the space occupied by the heat exchange reservoir assembly 20 to a certain extent. At the same time, effective temperature control is achieved through heat exchange between the refrigerant and the coolant entering the heat exchange reservoir assembly 20. The reservoir 21 and the heat exchanger assembly can be connected integrally, for example, by brazing.

[0152] In some embodiments, at least one heat exchanger includes a condenser 22 and an evaporator 23, with the liquid reservoir 21 located between the condenser 22 and the evaporator 23. Specifically, the heat exchanger group includes the condenser 22 and the evaporator 23 arranged in a stacked manner, with the liquid reservoir 21 located between the condenser 22 and the evaporator 23. Because the refrigerant flowing out of the condenser 22 is in a two-phase state, the built-in flow channel of the liquid reservoir 21 can be used to separate the liquid refrigerant and the gaseous refrigerant in the liquid reservoir 21. The liquid refrigerant then flows out through the bottom corner holes of the liquid reservoir 21 and flows to the evaporator 23, ensuring the evaporation capacity of the evaporator 23, ensuring that the refrigerant expands in the evaporator 23 and fully absorbs the heat of the coolant, thereby improving the heat exchange efficiency between the refrigerant flow path and the coolant flow path.

[0153] The liquid reservoir 21 is placed between the condenser 22 and the evaporator 23, and the flow paths between the liquid reservoir 21, the condenser 22 and the evaporator 23 are reasonably designed to ensure that the connecting flow paths between the condenser 22 and the liquid reservoir 21 and between the liquid reservoir 21 and the evaporator 23 are as short as possible. This helps to simplify the flow path within the heat exchange liquid storage assembly 20, avoid excessive loss of pressure and heat due to a too long flow path, and improve the flow smoothness of the refrigerant and the heat exchange efficiency with the corresponding coolant.

[0154] The coolant flow path flowing through the condenser 22 can be used to control the temperature and humidity in the passenger compartment, and the coolant flow path flowing through the evaporator 23 can be used to control the temperature of the battery system and the temperature and humidity in the passenger compartment. The remaining coolant flow paths can be equipped with additional heat exchangers or independent external radiators to control the temperature of the electric drive system so that the various functional systems of the vehicle can reach a good operating state, ensure the driving and riding comfort of the driver and passengers, and also ensure the stable and reliable operation of the vehicle.

[0155] In some embodiments, the liquid reservoir 21 is provided with a gas-liquid separation unit, and the gas-liquid separation unit is connected in series between the condenser 22 and the evaporator 23 .

[0156] Optionally, at least one heat exchanger further includes a subcooler 24, which is connected in series between the condenser 22 and the evaporator 23, wherein the subcooler 24 is provided between the condenser 22 and the liquid reservoir 21; or the subcooler 24 is provided between the evaporator 23 and the liquid reservoir 21. The provision of the subcooler 24 allows for secondary heat exchange between the condensed saturated liquid and the coolant, further increasing the subcooling degree of the refrigerant and reducing flash gas generated during the throttling process of the refrigerant, thereby helping to increase the evaporation capacity of the evaporator 23 and improving the heat exchange efficiency.

[0157] like Figures 1 to 2 The subcooler 24 is located between the liquid reservoir 21 and the condenser 22. At this time, a through hole is provided on the subcooler 24, which is used to connect the condensation outlet of the condenser 22 and the condensation inlet of the liquid reservoir 21, serving as a channel connecting the condenser 22 and the liquid reservoir 21, ensuring that the refrigerant flowing out of the condenser 22 can pass through the subcooler 24 (without heat exchange), enter and realize the separation of liquid refrigerant and gaseous refrigerant in the liquid reservoir 21, and the liquid reservoir 21 is also provided with a bottom corner hole connected to the subcooling inlet of the subcooler 24, ensuring that the liquid refrigerant flows through the bottom corner hole and the subcooling inlet in turn into the subcooler 24 for secondary heat exchange, and flows out of the subcooler 24 through the subcooling outlet on the subcooler 24, and the subcooling outlet is connected to the throttling inlet of the throttling device such as the expansion valve. Of course, in other embodiments, the subcooler 24 is located between the liquid reservoir 21 and the evaporator 23.

[0158] In some embodiments, the heat exchange liquid storage assembly 20 also includes a third valve 33, which is connected in series between the condenser 22 and the evaporator 23. The third valve 33 is used to control the flow of refrigerant from the condenser 22 to the evaporator 23. The third valve 33 is arranged at the inlet of the evaporator 23. On the one hand, it controls the flow of refrigerant entering the evaporator 23 to ensure that the refrigerant flowing out of the outlet of the evaporator 23 is in a gaseous state, reducing the content of liquid refrigerant, thereby reducing the possibility of liquid hammer caused by the refrigerant entering the compressor 10, and avoiding insufficient refrigeration due to too small a refrigerant flow rate, ensuring the cooling capacity of the evaporator 23, and improving the heat exchange efficiency. On the other hand, the low-temperature and high-pressure liquid refrigerant can be throttled through the throttle hole of the third valve 33 to become a low-temperature and low-pressure mist liquid refrigerant, which meets the evaporation conditions of the liquid refrigerant and thereby improves the evaporation heat absorption efficiency.

[0159] In order to further improve the integration level of the heat exchange liquid storage assembly 20, in one embodiment, the third valve 33 is integrated into the liquid storage container 21. It can be understood that, in combination with Figures 1 to 4 A throttling channel is integrated on the liquid reservoir 21, and the throttling channel and the built-in channel of the liquid reservoir 21 are independently arranged and do not communicate with each other. The throttling channel is provided with a throttling inlet connected to the subcooling outlet of the subcooler 24, and a throttling outlet connected to the inlet of the evaporator 23. In this way, the pressure regulation and flow regulation of the refrigerant flowing from the condenser 22 to the evaporator 23 can be achieved. At the same time, it helps to improve the integration of the liquid reservoir 21 and the third valve 33, reduce external pipelines, and thereby improve the integration level of the heat exchange liquid storage assembly 20 and reduce the space occupied by the heat exchange liquid storage assembly 20.

[0160] The refrigerant flow path is used to allow the refrigerant flowing into the third inlet to sequentially pass through the condenser 22, the liquid reservoir 21, the subcooler 24 and the evaporator 23 for heat exchange, and is also used to allow the refrigerant after heat exchange to flow back to the third outlet through the liquid reservoir 21, the subcooler 24 and the condenser 22 in sequence;

[0161] The heat exchanger can be a plate heat exchanger, that is, the plates are stacked and arranged, and the gaps between adjacent plates form a first inter-plate flow channel and a second inter-plate flow channel that are not connected to each other. The first inter-plate flow channel is configured as a refrigerant flow path for the flow of refrigerant, and is connected to the exhaust port 1204 of the compressor 10 through the corner holes on the plates. The second inter-plate flow channel is configured as a coolant flow path for the flow of coolant, and is connected to the corresponding functional system. The refrigerant and the coolant exchange heat through the plates.

[0162] Specifically, if Figure 1 to Figure 4Taking the subcooler 24 located at the liquid reservoir 21 and the condenser 22 as an example, the first inlet and the first outlet on the condenser 22 are connected through the first coolant flow path, and are used to connect the corresponding functional system, and then the refrigerant in the refrigerant flow path of the condenser 22 is used to perform heat exchange with the coolant in the first coolant flow path; the second inlet and the second outlet on the evaporator 23 are connected through the second coolant flow path, and are used to connect the corresponding functional system, and then the refrigerant in the refrigerant flow path of the evaporator 23 is used to perform heat exchange with the coolant in the second coolant flow path.

[0163] During ordinary cooling and heating processes, since the heat exchange liquid storage component 20 is connected to the compressor 10 through the condenser 22, the third inlet of the condenser 22 is directly connected to the exhaust port 1204 of the compressor 10, so that the refrigerant directly enters the condenser 22 through the third inlet (exhaust port 1204), is liquefied and releases heat to the coolant, completing the heat exchange. In order to avoid refrigerant leakage, a first sealing ring 73 is set between the third inlet and the exhaust port 1204.

[0164] In order to ensure that the refrigerant that has completed heat absorption flows back to the compressor 10 and re-participates in the circulation, the liquid reservoir 21 is provided with a through hole connecting the evaporator 23 and the condenser 22. The through hole connects to the part of the refrigerant flow path formed by the overlapping corner holes on the evaporator 23 and the part of the refrigerant flow path formed by the overlapping corner holes on the condenser 22, so that the refrigerant that has completed heat absorption passes through the evaporator 23, the liquid reservoir 21, the subcooler 24, and the condenser 22 in turn, and enters the compressor 10 through the air intake port 1203, cooperating with the refrigerant flow path in the compressor 10 to complete a cycle.

[0165] In order to ensure the reliability of heat exchange in the heat exchange liquid storage assembly 20, in one embodiment, a first thermal insulation pad is provided on the outside of the evaporator 23, specifically between the evaporator 23 and the liquid reservoir 21. When the refrigerant undergoes a vaporization reaction in the evaporator 23, the refrigerant is prevented from absorbing heat in the liquid reservoir 21 to a certain extent. When the first thermal insulation pad completely wraps the evaporator 23, the refrigerant is prevented from absorbing heat around the evaporator 23 to a certain extent, such as heat in the liquid reservoir 21 and heat in the external environment. It can also reduce the heat dissipation of the refrigerant that has completed heat absorption, thereby reducing the impact on the rear-end circulation.

[0166] In one embodiment, a second thermal insulation pad is provided on the periphery of the heat exchange liquid storage assembly 20 , and the second thermal insulation pad wraps the evaporator 23 , the liquid storage 21 , the subcooler 24 and the condenser 22 to improve the thermal insulation effect of the heat exchange liquid storage assembly 20 .

[0167] In addition, since the heat exchange liquid storage assembly 20 is connected to the compressor 10 through the condenser 22, the condenser 22 and the refrigerant outlet of the compressor 10 are directly connected to the air intake port 1203 of the compressor 10, so that the refrigerant directly enters the compressor 10 through the refrigerant outlet (air intake port 1203). In order to avoid refrigerant leakage, a second sealing ring 73 is set between the refrigerant outlet and the air intake port 1203.

[0168] Optionally, an oil detection tube 66 is provided at the top of the reservoir 21. The oil detection tube 66 is connected to the inlet of the third valve 33. The state of the refrigerant can be detected by connecting the oil detection tube 66 to an external test device. This facilitates detection of the oil in the reservoir 21. Optionally, the reservoir 21 is provided with a third sensor 63, which is configured to detect the outlet refrigerant temperature and / or pressure of the evaporator 23. Furthermore, the reservoir 21 is provided with a fourth sensor 64, which is configured to detect the inlet refrigerant temperature and / or pressure of the third valve 33. Furthermore, the reservoir 21 is provided with a fifth sensor 65, which is configured to detect the outlet refrigerant temperature and / or pressure of the third valve 33.

[0169] In some embodiments, the water cooling flow path includes a first flow path 201 and a second flow path 202 . The first flow path 201 is provided in the condenser 22 , and the second flow path 202 is provided in the evaporator 23 .

[0170] The present invention also proposes a thermal management system for a vehicle, which includes the aforementioned thermal management device 100 and / or the aforementioned compressor. The specific structures of the compressor and the thermal management device 100 refer to the above-mentioned embodiments. Since this thermal management system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0171] The present utility model also proposes a vehicle, which includes the aforementioned compressor, thermal management device, thermal management system and / or vehicle. The specific structures of the compressor, thermal management device, thermal management system and / or vehicle refer to the above-mentioned embodiments. Since the present vehicle adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described one by one here.

[0172] The present invention provides a thermal management device 100, which includes a compressor 10, a heat exchange and liquid storage assembly 20, multiple sensors, fixing bolts, multiple valves (which may be electronic expansion valves), a refrigerant filling port, a vibration isolation pad 72, and a support base 71. The compressor 10 includes a shell body 11 and an exhaust distribution member 12. The liquid storage and heat exchange assembly may include an evaporator 23, a condenser 22, a subcooler 24, and a liquid storage 21.

[0173] The exhaust distribution component 12 is provided with a first valve 31 , a second valve 32 , a first sensor 61 , a transparent window 122 , etc.

[0174] The liquid reservoir 21 is provided with a third sensor 63 , a fourth sensor 64 , a fifth sensor 65 , a third valve 33 , a first observation window 211 , a second observation window 212 , an oil detection tube 66 , and the like.

[0175] Thermal management device 100 includes a refrigerant circuit and a coolant circuit. These circuits operate in closed loops and exchange heat through heat exchangers (including an evaporator 23, a condenser 22, and a subcooler 24), effectively controlling the temperature of the vehicle's battery, electric drive, and passenger compartment. Condenser 22, subcooler 24, reservoir 21 (with integrated desiccant and filter), and evaporator 23 are stacked in a sequence, along the axis of compressor 10, moving away from it.

[0176] The condenser 22, the subcooler 24, the liquid reservoir 21 (with a desiccant and a filter integrated therein) and the evaporator 23 are integrated into a whole by welding or bolting, and the adjacent heat exchangers or liquid reservoirs 21 realize the flow of refrigerant through internal flow channels.

[0177] The compressor 10 and heat exchange liquid storage assembly 20 are connected to form a whole through a sealing ring 73 and bolts. The refrigerant flows and changes phases between the two to heat and cool the coolant flowing in from the outside. The different subcomponents of the compressor 10 are connected through sealing rings 73 and bolts. The coolant enters and exits through the inlets and outlets of the evaporator 23 and condenser 22, achieving heat exchange between the coolant and the refrigerant.

[0178] A connected refrigerant flow channel is formed on the side of the heat exchange liquid storage assembly 20 by welding or bolting. The welded flow channel inlet is connected to the exhaust distribution component 12 via a sealing ring 73 and bolts. A connected refrigerant flow channel is formed on the side of the heat exchange liquid storage assembly 20 by welding or bolting. The welded flow channel outlet is connected to the intake flow channel 1042 of the compressor 10 via a sealing ring 73 and bolts.

[0179] In combination with the above, the thermal management device 100 of the present invention has a first operating mode and a second operating mode.

[0180] In the first working mode: the high-pressure refrigerant compressed by the compressor 10 passes through the first valve 31 (fully open) and the exhaust distribution component 12, and then flows out through the sealing ring 73 into the condenser 22. The refrigerant releases heat into the coolant (which can be antifreeze) in the condenser 22. After flowing out of the condenser 22, the refrigerant passes through the internal through-hole of the subcooler 24 and enters the reservoir 21. The liquid refrigerant and the gaseous refrigerant are separated in the reservoir 21. The liquid refrigerant flows into the inlet of the subcooler 24 through the outlet of the reservoir 21. In the subcooler 24, the refrigerant and the coolant realize secondary heat exchange to further increase the subcooling degree of the refrigerant. After flowing out of the subcooler 24, the refrigerant enters the inlet of the third valve 33 integrated in the reservoir 21 from the outlet of the subcooler 24. The flow regulation and throttling process of the refrigerant are realized in the third valve 33. The refrigerant exiting the third valve 33 passes through the refrigerant flow channel integrated into the reservoir 21 and enters the evaporator 23, where it expands and absorbs heat from the coolant. Having absorbed heat, the refrigerant then flows out the side of the water-cooled evaporator 23 and into the heat exchanger and refrigerant flow channels on the side of the reservoir 21. The refrigerant passes through the sealing ring 73 and enters the intake flow channel 1042 of the compressor 10. The refrigerant is ultimately drawn into the low-pressure chamber of the compressor 10. This low-pressure refrigerant is pressurized by the high-pressure chamber of the compressor 10 and then flows out of the exhaust distributor 12, completing the cycle. In this mode, the second valve 32 remains closed. The coolant exchanges heat with the evaporator 23 and condenser 22. If the passenger compartment heat exchanger is connected to the coolant in the evaporator 23, cooling or demisting functions are achieved; if the passenger compartment heat exchanger is connected to the coolant in the condenser 22, heating or defrosting functions are achieved.

[0181] In the second operating mode, when the standard refrigerant cycle cannot meet the system's heating needs, a portion of the refrigerant passes through the first valve 31 (partially open) and flows out of the exhaust manifold 12. It then flows through the sealing ring 73 and into the condenser 22. The refrigerant entering the condenser 22 continues to flow through the condenser 22, the liquid reservoir 21, the subcooler 24, the third valve 33, and the evaporator 23, before finally being drawn into the compressor 10 through the intake duct 1042. Simultaneously, another portion of the refrigerant passes through the first valve 31 (partially open) and the second valve 32 (partially open) and enters the compressor 10 intake duct 1042. Within the compressor 10 intake duct 1042, the two refrigerants mix. After mixing, the refrigerant is again pressurized by the compressor 10 before flowing out to the exhaust manifold 12, completing the heating cycle. The return flow through the first and second valves 31, 32 increases the total refrigerant flow through the compressor 10, increasing the compressor 10 output power and improving the system's heating capacity. By adjusting the opening of the first valve 31 , the exhaust pressure of the compressor 10 can be adjusted, and the output power of the compressor 10 can be increased to achieve a rapid heating effect.
